Given numbers are 805, 783, 491, 206

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 491 are 491

Prime factors of 206 are 2 x 103

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 805, 783, 491, 206

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(805, 783) = 630315

GCD(805, 783) = ( 805 x 783 ) / 630315

= 805 / 783

= 805

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 805, 783, 491, 206 is 1
